Eaton WMZT2D04 4A 2-Pole 480 V Circuit Breaker

Engineered by Eaton, the WMZT2D04 4A 2-Pole 480 V Circuit Breaker is a compact, dependable overcurrent protector for 480-volt electrical systems. With a 4-amp rating and two poles, it safely interrupts two hot legs to defend equipment from overloads and faults.

• Part number: WMZT2D04
• Current rating: 4 A
• Poles: 2
• Voltage rating: 480 V
• Configuration: 2-pole device for dual-line protection in 480 VAC circuits
• Compatibility: Designed to integrate with Eaton panel boards and distribution equipment configured for 2-pole, 480 V protection

Why this matters: in high-voltage environments, precise current protection at 4 A prevents nuisance trips while guarding against overheating and electrical faults. The WMZT2D04 provides predictable trip behavior and rapid interruption when thresholds are exceeded, helping reduce equipment downtime and electrical risk.

Ideal use cases include safeguarding small motors, control circuits, or critical loads powered from 480 V, serving as the primary protection device for feeders or as a reliable replacement part in existing Eaton installations. The two-pole design ensures both live conductors are simultaneously isolated for safer service and maintenance.

Installation notes: verify compatibility with your Eaton panel or enclosure, ensure correct torque on terminal connections, and use the appropriate Eaton replacement parts to maintain system integrity and performance.

For engineers and technicians managing 480 V electrical systems, the WMZT2D04 delivers dependable protection without unnecessary complexity—a straightforward, purpose-built solution from a trusted brand.
